I too prefer to group related items together when I'm organizing drawers or storage compartments of any kind, and if an item has no similar items to live with, it ends up orphaned on a counter or surface somewhere, ultimately risking itself ending up in a junk drawer. But if it's an extra pair of glasses or something fragile, you don't want it getting tossed around other things like metal tools or otherwise damaging things. Other times, I leave things out of place in the open deliberately to remind myself to do something. This could be placing a bill or usually other paper items right at the end of the dinner table to force myself to remember taking care of it. Another example is leaving a cardboard box near the front door to recycle it later. It's intended to ugly up my space to bug me and take care of it. So, I often use my physical space as a natural to-do list of sorts. Works well!
